Title: Improvements in electromagnetic relays
IPC: H01H51/06
Filed: 1934-12-28
Abstract: 449,480. Electromagnetic switches. NEWMAN, H. A., 56, Springfield Road, Tottenham, London. Dec. 28, 1934, No. 37119. [Class 38 (v)] An electromagnetic relay for controlling a plurality of circuits for example, the high- and low-tension circuits of a magneto has such circuit control effected by means of an armature which moves between and bridges in turn two series of contact pins, studs or balls mounted in parallel insulating plates situated above and below the armature, the armature being adapted to be displaced by two electromagnets magnetically coupled together by a soft iron band, the whole relay being mounted on an insulating base. As shown in Fig. 1, the armature 7 is situated between upper and lower insulating plates 1. carrying rows of contact pins 2. The armature is raised from the lower set of pins to engage the upper set on energization of electromagnets 4 the upper end of the electromagnet coils being magnetically linked by a plate 5 of magnetic material. This plate may carry an " economy " resistance to be inserted into the electromagnet circuit to maintain the armature in displaced position after operation with reduced current in the winding. Further a lower E.M.F. is applied to the windings during the maintenance of the armature in its displaced position. The armature may carry contacting spring tongues 9 on its upper and lower face to improve contact between it and the fixed contact pins. Other forms of relatively fixed contacts may however be employed such as spring or gravitybiassed ball contacts or protruding pins operated by unbalanced levers. Connections to the contacts pass through grooves in the plates 1 and the supporting base, the grooves being filled in with paraffin wax.

Title: Device for use in the manufacture of aerosol dispensing containers
IPC: B65B7/28
Filed: 1973-08-06
Abstract: 1393481 Seaming; making aerosol dispensing containers COSTER TECNOLOGIE SPECIALI SpA 6 Aug 1973 [30 Sept 1972] 37171/73 Headings B3J and B3A A device for applying and seam folding a seat 25 of a dispensing valve 26 on an aerosol dispensing container 21 comprises a cylinder 1 accommodating a movable tubular body 5, an elongated hollow body 7 movable within the tubular body 5, suction means for retaining the valve seat 25 on the end of the hollow body 7, a tube 11 movable within the hollow body 7 for effecting outward movement of seam folding means 12 projecting from the hollow body 7. The cylinder 1, a container platform 20 and a guide 22 supporting spring biased blades 23 vertically adjustable relative to the platform 20 are carried by a frame continuously rotated about a vertical axis. At a first station, the cylinder 1 is lowered by a cam to enable the hollow body 7 to grip a valve seat 25 by suction continuously applied through the tube 11. After raising the cylinder 1 to lift the seat 25 from a shoot 28, a piston 3 connected to the tube 5 is lowered within the cylinder 1 until the tube 5 contacts the guide 22, whereupon a piston 4 connected to the hollow body 7 is lowered to cause the hollow body 7 to move through the blades 23 to position the seat 25 on the container 21. A piston 9 on the end of the tube 11 is then lowered within a head 8 attached to the hollow body 7 to move seam folding fingers 12 outwardly to deform the valve seat 25.

Patent GB-1324441-A (GB)
Title: Automatic vacuum operated clutch control device
IPC: F16D25/08
Filed: 1970-08-03
Abstract: 1324441 Clutch control F HAUBOURDIN and R ROLLAND 3 Aug 1970 [4 Aug 1969 14 March 1970] 37328/70 Heading F2L In a vacuum-operated clutch control for a motor vehicle wherein an electromagneticallyoperated valve 12 selectively connects a servochamber 9 to a vacuum supply 14 or to an air intake 15, gradual clutch engagement is obtained by controlling the flow of air into the air intake in response to accelerator pedal position. Air is drawn into the intake 15 through a duct 36 in a block 16 pivoted at 20 to a lever 21 which pivots about an axis 22 and is connected by a rod 24 to a diaphragm 1 of the servo-chamber 9. The flow of air into the duct 36 is controlled by a valve plate 39 pivotally connected at 28 to a lever 29 which is connected by a linkage 42, 43, 44 to an accelerator pedal controlled lever 46. A spring 31 acts between the levers 21, 29 to bias the latter clockwise. An adjustable stop 41 limits clockwise movement of the lever 29 and thus permits rapid initial light clutch engagement. Rapid clutch engaging movement of the diaphragm 1 is permitted until the block 16 abuts the valve plate 39 to close the inlet duct 36. Thereafter accelerator pedal depression moves the valve plate 39 right to open the duct 36 and permit further rightward clutch engaging movement of the diaphragm 1. The rate of clutch engagement is thus dependent upon the rate of accelerator pedal depression. When the clutch is fully engaged a guide rod 26 fast with the valve plate 39 and passing through a hole in the block 16, is engaged by the diaphragm 1 to lift the valve plate 39 off the duct 36. In Figs. 6 and 9 (not shown), the diaphragm abuts an additional rod adjustably connected to the valve plate to lift the latter off the duct at full clutch engagement. The electromagnetically operated valve 12 is normally biased by a spring 45 to the position in which it connects the servo-chamber 9 to the air intake 15. On energization of a solenoid 17 the valve 12 moves up against the bias of the spring 45 to connect the servochamber 9 to the vacuum supply 14. The vacuum supply may be provided by engine manifold depression or by an engine-driven vacuum pump. Electric control circuit.-Below a predetermined vehicle or engine speed the solenoid 17 is energized when a switch 19 is closed by releasing the accelerator pedal. Above the predetermined vehicle or engine speed a switch 19<SP>3</SP> in series with the switch 19 is opened to prevent energization of the solenoid 17 when the accelerator pedal is released. During gear-shift the solenoid 17 is energized by closure of a gearshift lever switch 19<SP>2</SP>. A switch 19<SP>4</SP> in series with the switch 19 is opened to permit clutch engagement when the gear-shift lever is in the neutral position. An additional air intake valve (58), Fig. 11 (not shown), is biased to an open position by a spring and is closed below the predetermined vehicle or engine speed by energization of a solenoid 57.

[Also in Division G1] In a photo-electric detector of holes in knitted fabric wherein the fabric is illuminated and/or observed at an acute angle to its surface and the detection of a hole is arranged to stop the machine, the angle is selected so that each thread shadows the interstice between that thread and the adjacent thread and light does not normally pass through. In the presence of a fault light may fall directly on a detector, on to a reflector which may return a beam along the original path or along a separate path, or on to a light guide leading to a detector. Sawtooth banking reflectors which may have planar or concave faces may be provided and' they may be pivotally mounted to keep the reflecting surface normal to the beam as it is scanned across the material. Alternatively, a line of individual reflectors each including a lens arrangement may be provided. The material may be illuminated by a fluorescent tube across its width and through a succession of screening louvres allowing light to impinge on the surface only at the desired angle. In a final embodiment a pencil of light is transmitted across the material surface along the path of a movable reflecting device arranged to scan across the material and any light passing through a hole is made to fall on a synchronously scanning reflector to be returned for detection beyond the edge of the material. Sizes of beam to produce minimal light intensity change during traverse are discussed. The light-guide in the arrangement previously referred to may have a saw tooth surface facing the material and may be terminated in a prism and lens system to feed any penetrating beam on to the detector.
